Signaling Lymphocyte Activation Molecule Receptors in Oncology
In the field of oncology, the Signaling Lymphocyte Activation Molecule (SLAM) family is emerging as pivotal in modulating immune responses within tumor environments. The SLAM family comprises nine receptors, mainly found on immune cell surfaces. These receptors play complex roles in the interaction between cancer and the host immune system. Research suggests SLAM’s role in both enhancing and dampening tumor-immune responses, influencing the progression and treatment outcomes of various cancers.

GABAA-ρ Receptors in the Central Nervous System
Gamma-aminobutyric acid (GABA) is known as the main inhibitory transmitter in the central nervous system (CNS), where it hyperpolarizes mature neurons through activation of GABAA receptors, pentameric complexes assembled by combination of subunits (α1–6, β1–3, γ1–3, δ, ε, θ, π and ρ1–3). GABAA-ρ subunits were originally described in the retina where they generate non-desensitizing Cl- currents that are insensitive to bicuculline and baclofen. The GABAA-ρ receptors are proposed to be involved in extrasynaptic communication and dysfunction involves reduced expression in Huntington's disease (HD) and autism spectrum disorders (ASD).

Contributions of lncRNAs in the Regulation of Cancer
Cancer is a prime example derived from a loss of homeostasis, primarily caused by genetic alterations both in the genomic and epigenetic landscape, which results in deregulation of the gene networks.

Bioactive Compounds of Dietary Origin on Colorectal Cancer
Colorectal cancer (CRC) is one of the most common causes of death and the third most diagnosed cancer worldwide, one of the main risk for developing CRC is a diet high in fat and carbohydrates which stimulates an inflammatory state increasing reactive oxygen species (ROS). Dietary Bioactive compounds have antioxidant proprieties and participates in gut microbiota modulation, decreasing reactive oxygen species and inflammation, both principal causes of cancer. These compounds can promote apoptosis and inhibit cell growth, proliferation, and migration of colorectal cancer cells modulating molecular pathways related to CRC. The multidisciplinary tratment of CRC requires a Nutritional intervention since patient nutritional status affects treatment response and the progression or recurrence of the tumor

Colorectal Carcinomas
Colorectal cancer is the third most diagnosed cancer, behind only breast and lung cancer. In terms of overall mortality, it ranks second due to, among other factors, problems with screening programs, which means that one of the factors that directly impacts survival and treatment success is early detection of the disease. Clusterin (CLU) is a molecular chaperone that has been linked to tumorigenesis, cancer progression and resistance to anticancer treatments, which has made it a promising drug target.

Heart Failure after Aortic Valve Replacement
Severe aortic stenosis (AS) carries a poor prognosis with the onset of heart failure (HF) symptoms, and surgical or transcatheter aortic valve replacement (AVR) is its only definitive treatment. The management of AS has seen a paradigm shift with the adoption of transcatheter aortic valve replacement (TAVR), allowing for the treatment of AS in patients who would not otherwise be candidates for surgical AVR.

Spermatogenesis and Andrological Diseases
Male infertility is a condition that has always been less studied and known than female infertility. Male infertility is increasingly present and increasingly diagnosed. The worldwide denasality can only be slowed if awareness campaigns are implemented on all the diseases that can alter fertile potential, especially in young adolescents.

Thyroid Autoimmunity and SARS-CoV-2 Infection
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological culprit of COronaVIrus Disease 19 (COVID-19), can enter the cells via the angiotensin-converting enzyme 2 (ACE2) receptor, which has been found in several tissues including in endocrine organs, such as the ovaries, testes, pancreas, and thyroid. Several thyroid disorders have been associated with SARS-CoV-2 infection [subacute thyroiditis (SAT), thyrotoxicosis, and non-thyroidal illness syndrome (NTIS)] and, in part, they are believed to be secondary to the local virus replication within the gland cells. However, as documented for other viruses, also SARS-CoV-2 seems to interfere with several aspects of the immune system, inducing the synthesis of autoantibodies and triggering latent or new onset autoimmune disease (AID), including autoimmune thyroid disease (AITD), such as Hashimoto Thyroiditis (HT) and Graves’ disease (GD). Several mechanisms have been hypothesized to explain this induction of autoimmunity by SARS-CoV-2 infection: the immune system hyper-stimulation, the molecular mimicry between self-antigens of the host and the virus, neutrophils extracellular traps, and finally the virus induced transcriptional changes of the immune genes; nonetheless, more evidence is needed especially from large long-term cohort studies involving COVID-19 patients, to establish or reject this pathogenetic relationship.

Transcatheter Aortic Valve Intervention Complications and Challenges
Since the first in man transcatheter aortic valve intervention (TAVI) performed by Dr. Alain Cribier in 2002 in a non-operable aortic stenosis (AS) patient, TAVI has changed the lives of so many patients for whom medical treatment was, up to then, the only option.

Gravitational Ischemia in the Brain
The physiological mechanisms for releasing and resolving gravitational ischemia in the brain, and their susceptibility to malfunction, may play an important role in a variety of neurological illnesses. An astronaut on a space walk in a micro-gravity environment may be susceptible to neuro-ocular symptoms associated with unopposed gravity-resistance mechanisms for partially preventing gravitational ischemia in the brain, and for attenuating its impact—mechanisms which may be required for normal brain physiology on Earth. Astronauts on the International Space Station typically breathe a mixture of gasses similar in composition to what they breathed on Earth, following the 1967 death of three astronauts, including Ed White, by fire on the Apollo 1 spacecraft, which was carrying 100% oxygen.
